BEST PRACTICES | 116
12.1.1 Seismic Force-Resisting Systems (1705.12.1.1):
Special inspections of Structural Steel in the seismic force-resisting
systems of building and structures assigned to Seismic Design
Category B, C, D, E or F shall be performed in accordance with the
quality assurance requirements of AISC 341-10
Exception: Special inspections are not required in the seismic forceresisting systems of buildings and structures assigned to Seismic
Design Category B or C that are not specifically detailed for seismic
resistance, with a response modification coefficient, R, of 3 or less,
excluding cantilever column systems.
12.1 Structural Steel (1705.12.1):
REQUIRED SPECIAL INSPECTIONS & TESTING
3.1 Torsional or extreme torsional irregularity.
3.2 Nonparallel systems irregularity.
3.3 Stiffness-soft story or stiffness-extreme soft story irregularity.
3.4 Discontinuity in lateral strength-weak story irregularity.
PLEASE PROVIDE THE NAME AND PHONE NUMBER OF
THE SPECIAL INSPECTION AGENCY AND INDIVIDUAL
PERFORMING THIS SPECIAL INSPECTION SERVICE IN
THE SPACE BELOW.
The structure is detached one- or two-family dwelling not exceeding two stories above grade plane and does not have
any of the following horizontal or vertical irregularities in accordance with Section 12.3 of ASCE 7-10:
3.
2.
The structure consists of light-frame construction; the design spectral response acceleration at short periods, S DS , as
determined in Section 1613.3.4, does not exceed 0.5; and the building height of the structure does not exceed 35 feet.
The seismic force-resisting system of the structure consists of reinforced masonry or reinforced concrete; the design
spectral response acceleration at short periods, S DS , as determined in Section 1613.3.4, doesn't not exceed 0.5; and
the building height of the structure doesn't not exceed 25 feet.
1.
Special Inspections for Seismic Resistance shall be required as specified in Sections 1705.12.1 through 1705.12.9, unless exempted by the exceptions of Section
1704.2. Also, the Special Inspections specified in Sections 1705.12.1 through 1705.12.9 are not required for structures designed and constructed in accordance
with one of the following (please check the exception below that applies to your project):
